Not working on Background after upgrade to RN 0.70 + R 18 (Android)

[punov]

Prerequisites:

• Was working well on stack: "react": "17.0.1" + "react-native": "0.64.3"
• We talk about Android only for now

Steps to reproduce:

• Upgrade to "react": "18.2.0" + "react-native": "0.70.6"
• Execute background timer
• Throw Android App on the background, switch to any other App

For a minute or two you can see successful logs in Logcat or anywhere else:

2023-01-03 14:59:42.273 12608-12812/ D/RNBackgroundTimerAndroid: setTimer for id: 695 for 5000.0 ms. Repeats: false
2023-01-03 14:59:42.292 12608-12812/ D/RNBackgroundTimerAndroid: clearTimer for id: 695

After 1-2 minutes it's no longer working.

@juanamd I know that your App is working fine for your production case,
it was also working fine for me before the upgrade.

I'm trying to figure the difference between your and my production setup and what exactly could cause the break.

I was able to fix it by providing more permissions to the Application,

"Apps" > <Select your app> > Remove permissions if app is unused turned OFF
"Apps" > <Select your app> > Battery > Unrestricted 

I can assume it will not suit some of your needs, but if you have to make your app unstoppable, it can save your day.
